3-204 Residential Zone District | Telluride Land Use Code

Section 3-204 Residential Zone District

3-204.A. Purpose. The purpose of the Residential Zone District (R) is to allow land to be used for permanent residential purposes and accessory uses. This zone has been applied to areas within the original Telluride townsite which were historically divided into lots of approximately twenty-five feet by one hundred feet (25' x 100') or twenty-five feet by one hundred seventeen and one-half feet (25'x117.5').

Development in the Residential Zone District should primarily be in-fill, or redevelopment and renovation of existing structures, with design review to ensure compliance with historic district guidelines. Public improvements, including streets, sidewalks, landscaping, parking and similar features, should be designed to meet neighborhood needs and opportunities.

3-204.B. Use Table. The uses permitted by right and the uses permitted on review in the Residential Zone District are as follows:

b. Accessory and secondary buildings, sixteen feet (16'). For structures which have at least fifty percent (50%) of their site coverage located on hillsides with a pre-construction grade or slope of fifteen percent (15%) or greater, no portion of the building, excluding chimneys, shall exceed a height of twenty vertical feet (20') above the pre-construction grade of the building’s site coverage, or the post-construction grade as measured from the exterior perimeter of the building’s site coverage (including window and door wells which extend greater than four feet (4') beyond the building’s site coverage perimeter), whichever is more restrictive.

3-204.C.11. Minimum Roof Pitch. For all buildings, one (1) unit of vertical rise to four (4) units of horizontal run unless modified or otherwise required by H.A.R.C.

a. For lots size of two thousand five hundred (2,500) square feet to three thousand one hundred twenty-five (3,125) square feet:

When all required parking is enclosed

0.45 - ([(Lot Area - 2,500) x 0.15]) / (3,125) = Maximum Percent Site Coverage

When all required parking is not enclosed

0.38 - ([(Lot Area - 2,500) x 0.15]) / (3,125) = Maximum Percent Site Coverage

b. For lots greater than three thousand one hundred twenty-five (3,125) square feet but less than seven thousand five hundred (7,500) square feet:

When all required parking is enclosed

0.42 - ([(Lot Area - 3,125) x 0.17]) / (7,500) = Maximum Percent Site Coverage

When all required parking is not enclosed

0.35 - ( [(Lot Area - 3,125) x 0.17]) / (7,500) = Maximum Percent Site Coverage

c. For lot sizes of seven thousand five hundred (7,500) square feet or greater, the site coverage shall not exceed twenty-five percent (25%), or when all required parking is enclosed, thirty-two percent (32%). For lots less than two thousand five hundred (2,500) square feet, the site coverage shall not exceed thirty-eight percent (38%), or when all required parking is enclosed, forty-five percent (45%).

d. Site coverage may be increased, by an amount up to ten percent (10%) of the lot area, so long as all of the following criteria are met:

(1) The site coverage increase area, for the purposes of this Section, means basement or cellar space having one hundred percent (100%) of its floor-to-ceiling height below the finished level of the adjoining ground (meaning entirely below grade). No portion of the building or structure’s site coverage increase area shall project above the finished grade except in the following instance: If the portion of building or structure associated with the site coverage increase area is located beneath ground floor porches or decks, then portions may project less than eighteen inches (18") above the finished grade so long as the H.A.R.C. finds the design treatment adequately screens the area between the porch or deck and the ground beneath the porch or deck. Detailed plans illustrating the treatment of the area beneath the porch or deck shall be submitted for H.A.R.C. review.

(2) The site coverage increase area, for the purposes of this Section, is measured where the exterior wall meets the foundation and includes those portions that project beyond the foundation wall of the above grade building and enclosed floor area.

(3) The site coverage increase area may not include elements visible from the exterior such as light wells, egress wells or egress stairs.

(4) The gross site coverage increase may not exceed ten percent (10%) of the lot area, up to a maximum of five hundred twenty-five (525) square feet.

(5) The site coverage increase may not be located less than three feet (3') from the property lines.

(6) Should the site coverage increase be applied to more than one (1) level below grade, where permitted, then it is counted separately for each level below grade regardless of floor height.

(7) The site coverage increase area shall not affect the Height of Building.

e. For lots of five thousand (5,000) square feet or less which contain a rated THAS secondary structure, the total maximum site coverage may be increased up to three percent (3%) by H.A.R.C. provided it finds the development application maintains or improves the historic rating of all historic structures on the lot.
